anti flashover compound coating
PRTV outside power equipment insulates with takes shape permanence
anti flashover compound coating, is a kind of electrical power
system uses the new electrical function material, it specially for
the electrical network and each round, loses, uses electricity the
customer to be lasting eliminates the equipment flashover
thoroughly the hidden danger then to design, It developed jointly
by the North China electric power academy of science with our
company successfully. The product has the unique chemical
composition and the structure, achieved and surpasses the heat
vulcanization silicon rubber physics electrical specification,
Overall performance and so on more outstanding water repellency
nature, as well as 20 years design service life has provided a kind
of new technical measure for the electric porcelaneous equipment
permanence counter- dirt. 1. Product Execution Qualification
This uses the North China electric power group company standard
"Outside the Power equipment To insulate with Takes shape the
Permanence Anti flashover the Compound Coating (PRTV) To use Leads
Then", With Hebei silicon valley chemical industry limited company
standard Q/HGH 019-2004 utside PRTV Power equipment Insulates with
Takes shape Permanence Anti flashover Compound Coating" to organize
the product the production and the construction.
2. Range of application
This product mainly uses in the electrical power system transformer
substation and the transmission line insulator, the power plant and
the electric power user changes outside the electricity equipment
as well as other electrical equipments insulates lastingly anti
flashover . After the porcelain (or glass) the insulator uses this
product, Forms the porcelain (or glass) the skeleton complex
effect, Enhances one kind of standardized disposition plan which
outside the power transformer equipment insulates. Is suitable in
alternating and direct circuit system rated voltage 1~750kV,
Environment Temperature -50¡¦~ +50¡¦, Under the contamination
condition moves outside the transformer substation and the
impractical transmission line equipment insulates antifouling,
Prevention flashover, Enhances the equipment outside to insulate
the rank.
3. Operation Guide
To porcelain (or glass) insulator superficial thorough clear dirt,
Removes the contamination, the fat and other attachments, After
waits the electric porcelaneous surface pure to be dry, May use to
spurt spreads or brushes spreads and so on to spread spreads the
method to carry on the construction, Coating thickness is 0.5 ~
0.6mm, the coating should leak proof spread, not dribble, does not
hang the silk, The surface is smooth, levels also does not have the
air bubble. Originally has used the RTV equipment, Should be clean
the unreliable attachment cleaning up, remove the contamination,
After uses the special-purpose processing medicinal preparation to
clean, Again executes spreads PRTV.
4. Package and Storage
This product packing in airtight metal container, When storing and
transportation should maintain dry and ventilates, Prevented all
day exposes to the sun, the rain drenches. The storage time is 1
year, Duplicate surpassed the storage time after to examine
qualified still may use when the coating uncaps the use, if has not
used up, Should cover securely immediately the airtight
preservation. PRTV outside power equipment insulates with takes
shape permanence anti flashover compound coating Technology
